Atix subscription manager on Debian 10 and 9

Problem: Looking for subscription-manager package to be installed on Debian 10 and 9 systems. we have some EOL machines that are required to be managed with foreman tool
below url provides the location for Debian 12 and 11. I dont find one for Deb 10 or v9
https://oss.atix.de/html/debian.html

also I did check the article-
Subscription Manager for Debian & Ubuntu on apt.atix.de - #17 by lentferj and added below entries:
wget -qO - https://apt.atix.de/atix_gpg.pub | apt-key add -
echo “deb https://apt.atix.de/Debian10/ stable main” >> /etc/apt/sources.list

but still I get below error on my Debian 10 system (that has connectivity to internet)
E: The repository ‘https://oss.atix.de/Debian10 stable Release’ does not have a Release file.
N: Updating from such a repository can’t be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.

Expected outcome: download and install subscription-manager

Foreman and Proxy versions: Foreman with katello was installed last week. so it is latest v3.7 (attached snippet)

Foreman and Proxy plugin versions:

Distribution and version:

Other relevant data:

We (ATIX) are providing clients for the latest, greatest OS versions and latest-1 for Debian/Ubuntu/SLES.

In case of Debian this is Debian 12 and Debian 11. Ubuntu 22.04 and 20.04. Latest Service Pack for SLES15 and SLES12.

Is it possible to re-enable the url https://apt.atix.de/Debian10/ that was working earlier.
so that I can download the package for Deb 10 atleast.
